9 Claims.

This invention relates to a pop-up type drain valve unit and more particularly to the [actuator connecting portion thereof] actuating means and connection thereof with the movable valve member in the unit.

Heretofore in the art of pop-up drain valves, the [actuator] actuating means, [comprises] has comprised [a tiltable solid unit] a ball rod having a drain exposed portion and a portion disposed exteriorly of the drain, [and] the latter portion being operatively associated with a suitable [actuating mechanism] lift rod unit [usual- 1y having] including a manually [actuable] operable member to effect [unit] tilting of the ball rod, to [effect] in turn efiect valve member elevation for draining. The drain exposed portion of the tilt rod is connected to a valve member which is movable upwardly and downwardly for opening and closing purposes respectively, the valve member seating by gravity for drain closing in the usual construction, and normally non-removably connected to the drain exposed portion of the ball rod.

A [The chief] primary object of the present invention is to provide a valve [end] member of such character that the structure can function as above described, and which [end] member is suitable for use with substantially ninety-eight per cent of all pop-up type drain units [actuators] now in use.

A further object of this invention is to provide a valve member which may be removably connected to the ball rod in the pop-up valve. unit, and easily assembled in operating connection therewith for actuation thereby.

A still further object of this invention is to provide a valve member which is operable by a ball rod in the usual manner, but assembled for positive operation thereby without removal of the ball rod necessarily resorted to in present constructions.

A further object of this invention is to provide a valve member including an end portionso constructed and arranged as to permit operation for normal drain opening and closing of said member regardless of the preferred positive connection thereof with the ball rod.

[The chief feature of the present invention resides in the actuator associated end of the pop up valve and its dual possible association with the actuator] The full nature of the invention will be understood from the accompanying drawing[s] and the following description and claims:

In the drawings Fig. 1 is a sectional view through a conventional pop-up valve and drain combination, the pop-up valve with the included invention being shown in elevation.

Fig. 2 is an elevational view of said valve taken at right angles to the valve as shown in Fig. 1.

Fig. 3 is a bottom view of the valve.

Fig. 4 is an enlarged sectional view taken on line 4-4 of Fig. 2 and in the direction of the arrows.

In Fig. 1 of the drawing[s], l0 indicates a sanitary fixture with drain outlet I l [discharging a drain] having a pop-up valve unit generally designated [2 connected thereto. The unit 12 comprises a plug 12a connected thereto in the usual manner, the plug in in turn being connected to a T I5. The discharge therefrom is by means of the tailpiece indicated at l3. In the middle branch of the T there is suitably mounted in sealed but tiltable relation as at] a ball or tilt rod M, the [actuator member] ball rod having the drain [enclosed] exposed end "3 and the [exposed actuable] end I! opposite thereto for connection with the usual lift rod unit (not shown).

The pop-up valve unit 12 also includes the valve member generally designated l8, including head or closure member 18a, stem portion I9, guide vanes 20, and lower stem extension or end 2|. The foregoing is in general old in the art.

Reference will now be [had] made to Figs. 1 to 3 inclusive wherein said extension or end 2| includes a diverging portion 22. Depending therefrom, in offset relation to the stem axis, see Figs. 1, 2, and 3, is the offset sidewardly open hook 23, substantially U-shaped in outline, see Fig. 2. The hook 23 comprises a body having the section 23a, which is connected to the portion 22, a lower section 230 and a vertical section 23b connecting the sections 23a and 23c. As shown in said figures, and Fig. 4, the [same] hook 23 in transverse section includes inclined sides 24, a semicircular end 25, and a flat opposite end 26, this formation rendering the valve member 18 including said hook portion more readily manufactured. Itwill be noted that the face 26 lies in a plane parallel to the azcis of the stem. portion and guide vanes, but offset therefrom. [Note that] The portion 22 may preferably terminate [terminates] in the same plane as the shoulder 21 of end or lower stem extension 21. It should be understood that the construction just above described is preferred but it is also contemplated that the juncture of the U-shaped hook 23 may be substantially above the shoulder 27, so long as the hook is offset as shown in Figure 1, and provides the necessary ball rod receiving opening as shown in Figure 2, the shoulder 27 being provided in the same relative position, see Figs. 1 to 3.

[With the actuator and parts assembled, and with the valve not applied, it will be obvious that if the valve be dropped into the waste line I! the shoulder 21 will be disposed above the actuator end l6 for valve elevation] [When the actuator and rod are to be connected the valve is turned and the rod now seats in the U-shaped hook or pocket, see Fig. 2 and as shown in Fig. 1.]

[In other words if the valve be dropped into the drain, it still will be actuable by the actuator because shoulder 21 overlies part i6. If it is turned sufliciently the rod seats in portion 23. Certainty of valve-actuator operative association for valve elevation is assured at all times] Assuming that the valve unit 12 has been suitably mounted in the drain outlet of the sanitary fixture 10, with the plug 12a, waste connection 1.2, T 15., and ball or tilt rod 14 in place, and that the valve member 18 is removed therefrom, assembly of the valve member 18, in the unit will be effected by dropping the said member 18 into the plug 12a. In a large number of instances, the U-shaped hook 23 will drop alongside the end 16 in the T 15, and thus the shoulder 27 will rest on the upper portion of said end. Subsequent tilting movement of the ball rod 14 will thus raise and lower the member 18 to open and close the plug 12a.

It may be however, that the section 230 of the hook .23 will come to rest on the upper surface o the end 16, which would normally prevent complete closure of the plug 12a, in which case, tilting movement of the rod 14 may be resorted to, to cause the section 230 to slide to one side or the other of the end 16, and permit the shoulder 27 to come into contact and rest on the said end. Under certain circumstances successive tilting movements of the rod 14 may be required, but in any event the section 23c will slide 7 the upper surface of the end 16, slight rotational movement of the member 18 taking place during such actuation and the shoulder 27 thus brought into engagement with theend v16.

In order to positively interengage the hook 23 and end 16 of rod 14, the valve member 1 8 may be turned by hand, into a position such as that shown in Figure 1, or reversely thereof. Thus unauthorized removal of the member may be prevented, positive opening and closing of the plug 12a efiected, and yet easy cleaning of the waste line accomplished, without disassembly of the rod .14 from the unit, by removing the valve member 18 with simple manipulation whereby to disengage end 16 of said rod from its position between section 230 of hook 23 and shoulder 27.

The spacing of the section 230 from shoulder .27 is such that a minimum amount of clearance is provided thereby and positive closure of plug 1.2a may be efiected,by proper manipulation of the ball or tilt rod 14.
